ASTM A513 Equivalent is DIN 17175 Grade 16Mo5, ASTM A513, ASME SA513 ASTM A513 specification covers electric-resistance-welded carbon steel tubing for use as mechanical and ornamental tubing.
ASTM A513 standard for carbon and alloy Electric Resistance Welded (ERW) mechanical tubing. It covers carbon steel grades starting at 1008 and higher in addition to specified alloy steels and can be classified Type1(Hot Rolled Electric Resistance Welded), Type 2 (cold rolled) and Type 5(Drawn Over Mandrel).
ASTM A513 ERW carbon steel pipe is widely used in a variety of mechanical and structural applications, including automotive manufacturing, agricultural equipment, furniture manufacturing, fitness equipment, scaffolding, railings, and more.
ASTM A513 erw carbon steel pipe covers round, square, rectangular, and special shape tubing.
